(ci. 221-23) This invention relates to devices -useful for opening sealed containers, and also serviceable as a spout for emptying such Vcontainers wholly or in part, as desired.

More particularly the present invention aims to provide a simple form of such device comprising a tubular member having an abutment flange and associated aperture-'forming means at one end, said means beingadapted to move the displaced material away from the aperture incidental to making said aperture.

Another aim of this invention is to provide a device of the type indicated in the preceding paragraph which when applied to the end of a sealed container automatically holds itself in position ready for the pouring operation.

Other aims of a tributory nature will be hereinafter disclosed or become apparent.from the following description of a typical embodiment of this invention, as illustrated by the accompanying sheet of drawings, while the concluding mately on he plane III-III 'of Fig. 1I.

Fig. IV is a horizontal section on the plane 3l IV-IV of Fig. II.

Fig. V is a fragmentary detail section hereinafter fully described; and,

Fig. VI is a perspective view showing a container with the opener and spout applied and in pouring position.

In the drawing, the reference character I designates a suitable container for fluid, such as oil for example, said container having sealed-in ends 2 and' being fabricated with a suitableimpervious inner coating 3. In addition, one of the ends, or both if desirable, is provided ,with a suitably scored and readily movable section 4l conveniently, although not essentially, of triangular contour; said section having an angular point 5 in proximity to the container body wall and the opposing base 6 in a plane at right angles to a radial line through the angular point I.

Referring now to the novel combination opener Il and spout of this invention, which is comprehensively designated l, the same preferably comprises a tapering tubular body portion or spout 48 having Aat the larger end. Q an eccentricallydisposed and preferably slightly angular related discous ange I0. This ange I0 has the sur- 'I shaped section to 'provide an outlet orifice I2 l0 of a contour corresponding substantially with the outline of the container end movable section l abovereferred to. In other words, the flange I0 is provided with an approximate rectangularly-related triangular-shaped cutter I3 prou jecting in a direction opposed to that of the spout 8, and the base I4 of which is at rightangles to a radial line through either the apex or point I5 of said cutter, or the angular point I6 of the flange I 0 caused by displacement and formation ofthe cutter I3. It is also to be noted .the unattached or flanking sides I1 of the cutter I3 are slightly beveled for the obvious purpose of presenting more effective edges for severing purposes, as hereafter set forth. Preferably, the 95 device is provided with an air vent I8 located as shown, to prevent formation of a vacuum in the container during emptying thereof.

In using the opener and spout 'I for emptying/f oil containers I fabricated of paper, ber or other suitable material with the ends retroverted and spun over inwards atli/tdseal-theends 2 in positiomfitis-tfrbeparticularly notedI the greater diameter of the eccentric ange I0 should beY slightly larger than the inner diameter of the 35 spun over retroversions I9 for the purpose later -on clarled, while the smaller diameter of said ange I0 caused by formation of the bevel edge II should substantially be the same as that of the inner diameter above referred to. Referring 4 rst to Fig. I, it will be readily understood that the user first places the point I5 of the cutter I3 in coincidence with the apex 5 ofthe container end movable section 4, and the opposing bevel edge II of the eccentriciiange I0 diametris or disrupt the movable section l, with the coat- 50 ing 3 within its confines, and simultaneously swing said section inwardly of the container I together with the related coating 3 and, by sliding of the fulcrum point 20 diametrlcally away from the apex\'5. Upon completion of the operation 56 just described, further pressure on the flange I l will cause the larger diameter beveled edge to annularly snap and bite into the citainer body retroversion il, as best indicated at 2i in lllg. V, whereby the opener and spout l will be firmly held in mutual engagement with the container. end 2. The parts 3 and i are thus prevented from moving back, by contacting the confronting cutter I3, into the province of vthe' spout origce I2, or interfering with outflow ofthe oontainerf as readily understood from Figs. II and VI.

From the foregoing it will 'be evident that other modes of applying the principle of this invention may bev employed, changes bdng effected as regards the details disclosed in order to adapt said invention to other usage. It is, accordingly, to be understood the following claims are intended to cover such equivalents, of the actual showing herein, as the state of the prior art will permit.

Having thus described our invention, we claim:

1. A container opener and pouring device comprising a tubular spout with an eccentrically related flange at one end adapted for forced iltment into the spun over end of a container, and a cutter member displaced outwardly from said nange within the connues of the adjoining spout end.

2. A container opener and pouring device comprising a tubular spout with an eccentrically related discous flange at one end, said flange having the circumferential edge surroundingly beveled, and a cutter member struck outwardly from said ange within the confines of the adjoining spout end.

3. A container opener and pouring device comprising a tubular spout with an eccentrlcally relateddiscousilange atoneend,laidnangehsving the circumferential edge surroundlngly beveled, and a cutter member struck outwardly from said flange within the confines of the adjoining spout end, said cutter member being of triangular cons tour and disposed in a plane substantially at right angles to the outer face of the nange.

4. A container opener and pouring device comprising a tubular spout with an eccentrically relatededlseous flange at one end, said flange havi0 ing th""circumferential edge surroundingly beveled, and a cutte member truck outwardly from said flange within the connesof thcai: joining spout end, said cutter being of triangular contour with its base in a line substantially dia- 15 metric of the flange with the flanking sides beveled to denne inwardly active severing edges.

5. A container opener. and spout device com-h prising a tapering tubular portion with an eccentrically-disposed and angularly-related discous 90 flange at one end, said flange having the circumferential edge beveled to define a larger diameter facing the tubular portion, and a triangular cutter member struck outwardly from the discous flange to provide an outlet orince therethrough, 25 said cutter member being disposed in a plane approximately at right angles to the discous ilange.

6. A container opener and spout device as deilned in claim 5 wherein the ilanking free edges are beveled to provide inwardly active cutter 30 edges, and the flange surrounding bevel edge is adapted to bite into the material of the container when said device is applied thereto.
